2.3 Fuel Savings and Comfort

Space heating can be accomplished with less input capacity when a radiant heating system is utilized, rather than with a conventional convective heating system. Why is this so?

A conventional, convective heating system, such as a unit heater or central furnace works by heating the air, which then indirectly heats the area and occupants. CRV-Series utilizes infrared energy to heat objects, people and surfaces directly, not the air. The warm objects and floor create a heat reservoir, which then re-radiates to the surroundings and also heats the air by convection.

The radiant energy received by the occupants, directly from the heater or indirectly from the surroundings via re-radiation, serves to increase the mean radiant temperature (MRT) of the space. In a manner similar to direct sunlight, the increased MRT allows the occupant to perceive a comfort condition at a reduced air temperature. The resulting reduced air temperature within the space provides the following fuel-saving advantages:

•Reduced stratification of air in the space.

•Reduced transmission heat loss due to lower tem- perature inside than assumed design condition.

•Reduced air change heat loss, to the extent that exfiltration through cracks or openings near the roof will be decreased because of decreased stack effect.

•Decreases the actual degree days experienced.

CRV-B-4, CRV-B-2, CRV-B-6, CRV-B-8 specifications

Roberts Gorden is renowned for its innovative heating solutions, particularly the CRV series of infrared radiant heaters, which include models CRV-B-2, CRV-B-4, CRV-B-6, and CRV-B-8. These heaters are designed to provide effective and efficient heating, making them ideal for various industrial, commercial, and agricultural applications.

One of the standout features of the Roberts Gorden CRV series is its advanced infrared heating technology. Unlike conventional heating systems that heat the air, infrared heaters warm objects and people directly, allowing for a more energy-efficient and comfortable environment. This makes the CRV series particularly effective in large spaces, such as warehouses, manufacturing facilities, and greenhouses.

The CRV-B models are engineered for versatility and can be mounted in various configurations, including horizontal and vertical placements, providing installation flexibility. Each model is available in different sizes and heating outputs, ensuring that users can select a unit tailored to their specific heating requirements. The CRV-B-2, for instance, is ideal for smaller spaces, while the CRV-B-8 offers higher power for larger areas.

Moreover, these heaters come equipped with advanced control systems that allow for precise temperature regulation. The units can be integrated with building management systems, enabling users to monitor and adjust settings remotely. This feature not only enhances comfort but also contributes to energy savings, as the heaters can be programmed to operate only during necessary hours.

Structural durability is another significant characteristic of the CRV series. Constructed with high-quality materials, the heaters are designed to withstand the rigors of industrial environments while maintaining optimal performance over time. The reflective surfaces enhance heat distribution, ensuring that warmth is evenly distributed throughout the space.

Safety is paramount with Roberts Gorden’s CRV heaters. They are designed with built-in safety mechanisms, including overheat protection and automatic shut-off features to prevent accidents.

Overall, the Roberts Gorden CRV-B-2, CRV-B-4, CRV-B-6, and CRV-B-8 models exemplify cutting-edge infrared heating technology, delivering effective, efficient, and reliable heating solutions tailored to diverse applications. With a combination of flexibility, advanced control capabilities, and safety features, these heaters are an excellent choice for anyone in need of powerful heating solutions.
